Defining Pressure in the Process Parameters of a Pressure Vessel

In the specifications or standards for various pressure vessels, terms such as working pressure, maximum pressure, and design pressure are frequently encountered. Here are their definitions: (1) Operating Pressure: Operating pressure, also known as working pressure, denotes the pressure at the top of the container during regular process operations, excluding hydrostatic pressure. (2) Maximum Working Pressure: This refers to the highest pressure that the top of the vessel may experience during process...

Understanding Pressure Vessels: A Comprehensive Overview

A pressure vessel is a closed apparatus designed to contain gas or liquid under a specific pressure. The criteria defining pressure vessels involve a maximum working pressure equal to or greater than 0.1MPa (gauge pressure). These vessels come in fixed or mobile forms, serving as containers for liquefied gas or gas with a pressure-volume product equal to or exceeding 2.5MPa·L. Additionally, they can hold liquids with a maximum operating temperature equal to or greater than the standard boiling...

Optimizing Heat Exchanger Performance with Chemical Cleaning

Heat exchangers play a vital role in a myriad of industries such as petroleum, chemical, light industry, pharmaceutical, and energy production. However, prolonged operation of these heat exchangers leads to the accumulation of dirt within, causing a reduction in the cross-sectional area of the internal passages. This accumulation, in turn, results in decreased cooling water flow, lowered pressure, and potential downtime, eventually leading to production shutdowns. Moreover, it poses serious safety...
